ROAD SHOULDER AND WEED ATTACHMENT FOR ROAD SCRAPING MACHINES.

Application filed September To all whom it may concern:

Be it known that I, JOHN A. BLAoK, a

V citizen of the United States, residing at of road working machinery and has more particular reference to an attachment to a scraping machine whereby road shoulders and weeds may be effectively cut for providing a smooth road surface.

The primary object of the invention is to provide an attachment of this character whereby the shoulders and weeds that generally form and grow respectively at opposite edges of the road may be cut therefrom during the scraping of the road surface.

An additional object of the invention is to provide an attachement that may be readily associated with or removed from the blades attached to the old forms of scraping machines.

With the foregoing and other objects in View as the nature of the invention will be better. understood the same comprises the novel form, combination and arrangement of parts hereinafter more fully described,

scraping machines.

shown in the accompanying drawing and claimed.

'In the drawing wherein like reference characters indicate corresponding parts in Figures 1 and 2:

Figure 1 is a rear elevational view of the scraping blade of a conventional form of road scraping machine with which is associated my road shoulder and weed cutting attachment.

Figure 2 is a. detail vertical sectional view taken substantially upon the line 22 of Figure 1, and

Figure 3 is a modified form of the attachment per se.

Now having particular reference to the drawing, 5 designates the cutting blade of one of a number of different forms of road In carrying out this invention, the blade 5 is provided in longitudinally spaced relation at the outer edge and upon the rear side thereof with L- shaped brackets 6 which are preferably three in number. These brackets being riv- 9, 1924. Serial No. 736,734.

eted, bolted or otherwise secured to said cutting blade.

Rigidly secured to the projecting legs of the bracket 6 through the medium of bolt and nut connection is a horizontal flat bar 7 the outer end of which is down'turned as at 8. Pivotally secured to this down turned end 8 of said bar 7 is the upturned end 9 of a horizontal cutter bar 10. The pivotal connection between these ends of the bars being designated 11.

The upturned end 9 of the cutter bar 10 is provided with an arcuate series of openings 12 for selective registration with an opening in the downturned end of the bar 8 whereby the cutter bar may he so disposed and maintained through the medium of the bolt connection 13 as to position the cutting edge 14 of the bar at various positions with respect to the scraping blade 5 of the machine.

In the form of the invention shown in Figure 3, the bar 7 which in this instance is also a cutter bar is formed integrally with the cutter bar 10 and in offset relation thereto through the medium of the connecting portion 15. Each of these bars is provided with spaced openings for allowing the same to be secured to the bracket 6 of the scraping blade 5. The cutting edges of the bars are so arranged that the cutting edge of one bar will be in operation when the other bar is secured to the scraping blade 5 and vice versa.

From the foregoing description when considered in conjunction with the accompanying drawing it will be apparent that I have provided a highly novel, simple and efiicicnt form of road shoulder and weed cutting attachment for road scraping machines and one that I believe will meet with all the requirements for successful usage.

Minor changes may be made in the invention without departing from the spirit and scope of the appended claims.

Having thus described the invention, what I claim is 1. In an attachment for road scraping machine blade, a bar secured in horizontal position upon the blade adjacent the outer end thereof, and a cutter blade carried by the outer end of the bar in offset horizontal alignment therewith.

2. In an attachment for road scraping machine blade, a bar secured in horizontal position upon the blade adjacent the outer end thereof, a cutter blade carried by the outer end of amber in offset horizontal alignment therewith, and means whereby the pitch of the cutter blade may be Varied.

3. In an attachment for road scraping machine blade, a plurality of spaced brackets secured to the rear side of the blade at one end thereof, a bar secured in horizontal position to said brackets and provided with 1 ing the ends of the bar and blade in adjusta- 15 ble relation.

In testimony whereof I affiX my signature.

JOHN A. BLACK.
